Although the rules of wargame deduction are simple, it is not so easy, Zhu Yunwen first led everyone to make a simple, first deduce the role of the Western Route Army.

"Let's set the basic elements of the deduction, and if it passes, we can proceed to the next step."

"The commander of our side is the emperor, and the commander of the Yuan army is Timur, do you have any objections to this?"

Xu Huizu said: "It may also be the heir of the Northern Yuan." ”

"This is indeed possible, but Lone thinks that the early stage may be the heir of the Northern Yuan Dynasty, such as the beginning of the fifth year of Hongwu, the Yuan army in the north east to Kaiyuan, west to Gansu, Ningxia and other places to harass our dynasty, in Lone's view, in fact, it is more like a vent of anger, especially the three years of Hongwu The heavy blow has just passed, the Northern Yuan Dynasty cannot recover so quickly, Lone feels that this period of time should be led by the heir of the Northern Yuan, from a military point of view, the harassment during this period is meaningless, and this time is for the war horse, It's not a good time to go on an expedition. ”

"Your Highness also has a point."

"So let me ask the question, what was the role of Timur during this time? Where will he be located? ”

"Your Highness, the last general thinks that even if Timur does not agree to this kind of harassment, he will be in a leading position, because in such a large area of harassment, there are not many troops needed, and a certain amount of coordinated command is required. Therefore, he will not be in Helin, but from the direction of attack of the Yuan army, it is biased to the west, and from the point of view of military command, he and the front line cannot exceed 5 to 10 days' horse journey, that is, between 400 and 800 li, and should be in the south of Monan, eastern Gansu, on the periphery of the Hetao grassland, to observe the movement of our army. ”

"What do you think?"

Geng Xuan stood up and said, "Your Highness, I think there is also a possibility that Timur was abandoned because he opposed this strategy, and he is located in Horin. ”

"What about the others?"

"The last general agrees with Wei Guogong's opinion." "The minister agrees with Geng Xiaohouye's opinion." Everyone interjected.

"Okay, because both of these situations exist, they are both used as the basis for deduction, and Tan Bo will record them on the blackboard."

"Yes, Your Highness."

"Then, our army is ready to chase the dead and chase the north, when do you think the Yuan army will get the news that our army is going to attack."

"Our army was assembled in three parts at that time, the Middle Route Army was at Yanmen Pass, the East Route Army was at Juyong Pass, and the West Route Army was in Lanzhou. At that time, the Northern Yuan Dynasty was not without the possibility of a comeback, and there must have been many spies, so Lone thought that when the King of Zhongshan came out of Yanmen Pass, it could be considered that the Northern Yuan spies knew. If a single exploration horse, from Yanmen Pass to Helin at the fastest only takes about 5 days, because along the way can change horses, change people, if the expansion of Timur in the periphery of the Hetao, it can be considered that it only takes 3 days to know the news of the assembly of the army of the King of Zhongshan, at this time, Liang Guogong should not have left the Great Wall. At this time, what will Timur do? ”

Chang Sheng stood up and said: "Your Highness, according to the assumption of the position of the first two expanded Timur, if he is on the periphery of the Hetao, he will order the army to retreat and block the Yemachuan generation to obtain further news of our army. In addition, he would gather all the remnants of the Northern Yuan army in Lingbei and wait for our army to be exhausted and fight a decisive battle with our army. If he is in Helin, he will get the news in 5 days, then he can also mobilize the Yuan army Yemachuan to block it, and then order the Yuan army to season in Lingbei. This difference is not huge. ”

"So, how long is that?"

Chang Sheng said: "If the last general is to expand Timur, if he gets the news on the outskirts of the Hetao, he will quickly return to Holin, and it is estimated that it will not take more than 10 days to reach Horin, so that there are still 7 days before the time when Liang Guogong arrives at Yemachuan, and he can also issue orders on the way." Therefore, at the latest in Helin, that is, our army went out of Yanmen Pass, and when our army's advance had not yet arrived at Yemachuan, the Yuan army could make the decision to clear the field and fight a decisive battle in Lingbei. When King Zhongshan arrived in Lingbei, it was 68 days after our army left Yanmen, so the Yuan army had 50 days of assembly and preparation, it is conceivable that the Yuan army fought with the attitude of the last battle, and it can be considered that its strength was far above our army, plus the fatigue of our army, so the defeat was not unexpected. ”

"If he is in Helin, then he will know the news of our army's departure from Yanmen 2 days later, but he will be uncertain about the direction of our army's attack, but at the latest after the battle of Yemachuan, he will make the same decision, gather the Yuan army, and prepare for war, at this time the time of the Yuan army is 48 days, so there is not much difference."

Yun Wei looked around and said, "The founding prince has analyzed very well, what questions do you still have?" ”

"Nope." There is no opinion on everyone.

"Okay, after the analysis of the founding prince, no matter where Timur is, there is not much change in the date, time and place of preparation for the final decisive battle. That's simple, will he mobilize the Gansu Yuan army to return to Helin? Will the Gansu defenders obey orders? How many defenders are there that can come back? ”

Qi De stood up and said, "Your Highness, the Yuan army in Gansu is about 50,000, but it is distributed in Liangzhou, Yongchang, Jiuquan, Yijinai Road and other places. The order of the Northern Yuan is generally the most observed, considering the actual situation, only the elite cavalry can be dispatched, estimated at about 20,000 cavalry, considering the time of going back and forth, from receiving the order should be able to gather in about 12 days, assemble to Yiji Nai Road, from Yiji Nai Road to Helin about 1,500 li, the distance to Lingbei is about the same, 20,000 cavalry will take about 20 days. If Kuangku Timur was on the outskirts of the Hetao, it took him three days to receive the assembly of the Central Route Army, and if there was no Western Route Army to attack at this time, then he would most likely have mobilized the Gansu defenders, because he had fought in Ningxia, Gansu before fleeing to Helin, so if he ordered the transfer, it was not expected that there would be much of a problem. From Hetao to Yiji Nai Road, it takes 3-5 days for the heralds, so after the king of Zhongshan leaves Yanmen, the Gansu defenders will gather 20,000 cavalry to return to Lingbei within 20 days, and arrive in Lingbei after 20 days, and they can rest for nearly a month, which will have a decisive impact on the decisive battle of Lingbei. ”

"If Timur was in Helin at that time, then it would take at least 15 to 20 days to make a decision, and if the order was added, the assembly time of the Gansu defenders would be about 40 days, so there was little point in returning to Lingbei at this time. So at this time, if there is no Western Route Army, it is also possible. ”

Xu Huizu put forward a different opinion: "It's different, if before the decisive battle in Lingbei, the expansion of Timur let the Gansu Yuan army return to the periphery of the Hetao to block our army returning to the division, and then expand the division Timur to pursue from behind, our army will be in danger." ”

Song Xuan interjected: "Does the Mobei Yuan Army have so much strength? You can defeat the middle route army and then pursue, after all, our eastern route army will also arrive in Helin 1 month later. ”

Chang Sheng said: "The Yuan army is a soldier of the whole people, and its strength of recruitment and deployment is unimaginable, and in addition, the Eastern Route Army reached the area of the Tura River and the Aruhun River, and the Yuan army barbarian Harazhang battle, and the casualties were equal. So if there is no Western Route Army, then the Central Route Army may have suffered even greater losses. ”

Zhu Yunwen stood up, swept around, and asked, "Do you have any other opinions, you can speak freely, this is a war game deduction, not aimed at anyone." ”

Everyone was interested in the discussion just now, and they all expressed their opinions. "How could the Yuan army be assembled so quickly?" "Will Timur's reaction be so fast?" "Is the speed of the Yuan army exploring the horse so fast?"

......

The discussion lasted until noon, and everyone continued to discuss while eating, until the evening, everyone basically reached a consensus that the Western Route Army was necessary, and it needed to attack half a month before the Central Route Army attacked, so as to effectively drag the Yuan Army.

In the next few days, everyone forgot to sleep and eat, deduced various situations, and found that the imperial court at that time underestimated the war potential of the Yuan army, and did not consider the impact of the decisive battle in Mobei on the physical strength of our army, as well as the physical strength bonus of the Yuan army's internal operations.

At this point, Zhu Yunwen also helped, he pointed out that the Northern Yuan and the Xiongnu are different enemies, the territory of the Northern Yuan is vast, and the troops that can be requisitioned are far greater than the Xiongnu, starting from Genghis Khan, a large number of herdsmen regard themselves as Mongols, but the Xiongnu are different, and there are many internal falls, and there are strong enemies outside, so it was a bit risky to go to the Northern Yuan at that time, maybe it would be better to be more fully prepared.

Zhu Yunwen will go to report the progress to Zhu Yuanzhang every day, and he also made a set of war game deduction tools in the side hall of the Qianqing Palace, Zhu Yuanzhang will listen to Zhu Yunwen's description every day, this method is actually not unusual, because he also analyzed it this way when he studied the battle situation himself, but he did not use so many people, and he did not calculate so accurately, and did not consider the number of people, equipment, physical strength, transportation, grain and grass, weather and other factors like this.

Zhu Yuanzhang thought about it for a while and said: "This method is really good, but it is not easy to be so accurate, but it can indeed reduce the dependence on genius generals, or reduce their burden." This analysis of the decisive battle in Lingbei really gives people a refreshing feeling. I think it's good, I can do it on a larger scale, and in two days I will go over to take a look at the spot, and I will bring Song Guogong, Ying Guogong and Liang Guogong, as well as a few of your uncles, they are also going to be vassals, and you will be sent when the time comes. ”

Zhu Yunwen said yes, and finally breathed a sigh of relief, he came over to talk to Zhu Yuanzhang every day, in fact, he also came to get a preventive injection first, because this involved a lot of decisions back then, and the people at that time were all high-powered, and the most important thing was that the imperial grandfather in front of him had to let him accept it, otherwise, he was fine, and others would be unlucky, but it looks good now.

He thought well, if this matter was not done by Zhu Yunwen, Zhu Yuanzhang would have pulled it out and cut it down, and a group of little dolls dared to question the decision-making of the imperial court, hehe, I don't want my head.

Soon the 7-day deadline was up, and Zhu Yunwen notified the others early, made full preparations, and went to the war room of Zhan Shifu early to wait.

After the court meeting, Zhu Yunwen accompanied Zhu Yuanzhang to the Zhan Mansion in a dragon chariot, followed by Zhu Ao, the king of Su, Zhu Zhi, the king of Liao, Zhu Quan, the king of Qing, Zhu Quan, the king of Ning, as well as Feng Sheng, the Duke of Song, Fu Youde, the Duke of Yingguo, and Lan Yu, the Duke of Liangguo, and walked to the Zhan Mansion from the mighty people.

These four kings and Zhu Yunwen are not very old, but Zhu Yunwen can sit with Zhu Yuanzhang, but they have to walk, and they can't help but be a little angry. Because they are about to become vassals, the King of Liao and the King of Ning are fine, and the soldiers of Liaodong and Daning are strong, but the King of Su and the King of Qing are in Ningxia, Gansu, which is already the northwest border of the empire, and the military strength is not strong, so they are not very willing and a little sad.

When they arrived at the war room, all the irrelevant personnel withdrew, and there were sentry posts all over the vicinity, and no one was allowed to approach.

As soon as they entered the war room, everyone was amazed by the size and sophistication of the sand table on the large table. The sand table is not a new thing, it is said that when Qin Shi Huang destroyed the Six Kingdoms, Qin Shi Huang personally studied the situation of various countries, and with the assistance of Li Si, deployed a large-scale annexation war. Even in the mausoleum, a large topographic model was built, which not only included mountains, hills, cities, etc., but also simulated rivers and seas with mercury, and used mechanical devices to circulate mercury. Later, Shen Kuo of the Song Dynasty once mentioned the method of making sand tables out of wood in "Mengxi Bi Tan". But the sand table in the war room is made of clay, which is not only easy to shape, but also easy to make. Although Zhu Yuanzhang heard Zhu Yunwen say about the sand table, he was still very shocked at first sight, and immediately said: "Yunwen, this sand table looks good, just put it in the Qianqing Palace, and the imperial grandfather can see it at any time." ”

"Grandpa Huang, the time is too short, this sand table is not very accurate, I plan to make a bigger one, more accurate to put in the Qianqing Palace, is this okay?"

"How long will it take?"

"2 to 3 months." Zhu Yunwen peeked at Qi De, saw that he stretched out 2 fingers, and then turned into 3, and said knowingly. ”

"It's too long, let's move this to the Qianqing Palace first, and when the new sand table is ready, I'll return it to you."

"Okay, listen to Grandpa Huang." Yun Wei said helplessly.

Zhu Yuanzhang twisted his beard and smiled: "Okay, let's take a look at your wargame deduction." ”

Zhu Yunwen said: "Grandpa Huang, please sit down, let me introduce you." In fact, the wargame deduction is best on the sand table, because it is more intuitive for the mountains and rivers, but the conditions are limited, so we will deduce it on the map this time. ”

"Lonely here to introduce the jade, please ask the imperial grandfather, uncles, and princes to give me some guidance."

.......

Zhu Yunwen introduced the process and results of this deduction, and observed the expressions of the people around him, King Ning and King Liao looked very interested, and they were more concentrated; King Qing and King Su look plain, and it can be seen that the two are not interested in military affairs; Feng Sheng, the Duke of Song, was a short old man in his fifties, with a pair of eyes like foxes, which fully showed the master's astuteness and suspicion; Fu Youde, the Duke of Yingguo, is in his fifties, with a stout body and a capable appearance, showing his bravery and fearlessness with his gestures; Liang Guogong Lan Yu is also in his fifties, but he looks much younger, a red-faced man, tall, but there is an impatient look on his face, and there seems to be a kind of contempt in his eyes when he looks at Feng Fu and the others.

The deduction time is very long, and there are some problems in the middle, Zhu Yunwen also asked Xu Huizu and Chang Sheng to add, and the deduction process was written on the blackboard by Tan Bo, so that everyone could see it at a glance. It was deduced until noon dinner time, Zhu Yuanzhang asked him to pass on the meal, he was a simple person, he ate very simply, and everyone paid attention to eating. After eating, everyone continued to listen to Zhu Yunwen's deduction until the end of the deduction.

In the end, Zhu Yunwen made a summary: "Judging from the process of this deduction, there are the following conclusions:"

"First, this sortie may be a bit hasty, and the intelligence is not complete."

"Second, the Western Route Army is necessary, but it may be better if the time for the attack can be advanced."

"Third, the Middle Route Army needs to be strengthened, especially in the decisive battle in Lingbei, the hinterland of the Northern Yuan, the Northern Yuan is facing a situation of fighting against the water, and its strength is much stronger than our army."

"Fourth, the sortie of the Eastern Route Army was too late and did not play its due role."

After Zhu Yunwen finished speaking, he turned his head to Zhu Yuanzhang and said, "Your Majesty, Yunwen has finished introducing him, please correct the emperor." ”

Zhu Yuanzhang actually knew most of the results, but this time it sounded different, and it was a little uncomfortable, because he was the decision-maker of this attack, and now he was analyzed in such detail, and he was a little annoyed, but fortunately, it was his grandson, so forget it. However, he was also observing everyone's expressions, and he found that the people in Zhan Shifu, including Xu Huizu and Chang Sheng, all respected Zhu Yunwen very much, which was not only because of his identity, but also because of his identity, but also because Zhu Yunwen had something to admire, which made him very pleased. Sun Er was able to make this thing, and find the corresponding manpower, analyze it reasonably, and finally talk eloquently in front of the elders and heroes on the scene, and there was no stage fright, which Zhu Yuanzhang was also very satisfied with, of course, what he didn't know was that Zhu Yunwen often explained the battle situation in his dreams, and he had a good grasp of terms and rhythm. He is relatively satisfied with King Ning and King Liao, and it can be seen that they should have something to do after they become vassals. For King Qing and King Su, there was a slight disappointment. For the three princes, he focused on observation, and found that Feng Sheng didn't say anything, Fu Youde was okay at first, but he didn't have patience later, and Lan Yu had an expression of watching children hide and seek from beginning to end, which made him a little angry.

Zhu Yuanzhang raised his hand, everyone quieted down, Zhu Yuanzhang cleared his throat and said: "The imperial grandson has already explained the war games of the decisive battle in Lingbei, although there are some flaws, but I am still satisfied on the whole, let's talk about my opinions." ”

"Returning to my father," Zhu Quan, the king of Ning, hurriedly said: "Yun Wei said very well, this time let Erchen open his eyes, after Erchen arrives in Daning, he must make a sand table, and conduct war games on the situation, better mobilize the army, hold the vassal country, and defeat Mongolia." ”

"So is Erchen." The kings of Liao, Ning, and Su all continued.

Zhu Yuanzhang was very happy and said: "A few of you are about to become a vassal, although you are the same age as Yun Wei, you are indeed uncles, you must guard the frontier and share your worries for Yun Wei." ”

"The retainers obey." The four kings fell to their knees and received the decree.

"How many of you? What about Song Guogong, Ying Guogong and Liang Guogong? ”

Lan Yu preemptively said: "This sand table is good, but the end of this deduction will feel that it is a war on paper, if this deduction can solve the problem, what do you need the soldiers to do in the bloody battlefield, compare and draw on the map, see who has more soldiers and fewer soldiers, you don't have to fight, give the enemy a war game, and the enemy will surrender." Therefore, the last general thinks that this war game deduction is not very practical, for example, it is difficult to calculate the time of climbing mountains and crossing rivers......".

Lan Yu talked for a long time, and his voice echoed in the war room.

Zhu Yuanzhang's face did not change, and when Lan Yu finished speaking, he was silent for a while and said to Zhu Yunwen: "Yunwen, you heard the words of Liang Guogong, what do you think?" ”

Zhu Yunwen arched his hand and said: "Back to the emperor, deduction is not a substitute for command, the beginning of Sun Tzu's Art of War says: 'The husband is the victor without a fight, and he has to count a lot; The temple is not victorious without a fight, and it is considered to be less. More wins, less wins, and nothing counts! Bingsheng attaches great importance to the temple calculation in front of the station, and Yun Wei just carries forward this idea, quantifies various factors, and then speculates and evaluates. I think this will help you make strategic decisions, but of course, you can't be completely right, you need to accumulate slowly, and all other factors can be accurately measured, and at that time, I thought that all strategic decisions had to go through wargames to make a final decision. ”

Lan Yu was stunned for a moment and said, "That's what the Soldier Saint said, but I don't think this deduction is good. ”

Zhu Yunwen said sincerely: "Yunwen also just had this idea, and it needs to be gradually improved, and if the Duke of Liangguo has time, he can come and deduce it together." ”

Lan Yu's nose "snorted" and did not speak.

Zhu Yuanzhang's face was a little unsightly, so he turned his head and asked Feng Sheng and Fu Youde what they thought.

Feng Sheng coughed and said slowly: "Your Majesty, the emperor's grandson is talented and intelligent, and the war game deduction is also wonderful, and I admire it." ”

Fu Youde was silent for a while and said: "Your Majesty, the minister understands the first half, but the second half doesn't understand, and those numerical calculations make the minister's brain a little confused." ”

......

The monarch and the ministers played the right game for a while, and they were all in favor of Yun Wei in general, except for Lan Yu.

In the end, Zhu Yuanzhang was a little tired, since Zhu Biao's death, he has not been in good health, so he said: "Let's stop here today, Yun Wei, move the sand table to the Qianqing Palace for a while, today's deduction will be sorted out, written into a chapter, let me take a look, and the wargame deduction still needs to be perfected, this will also be handed over to you." In addition, the Duke of Wei, the Founding Duke and a few of you have all worked hard, all of them have meritorious, and everyone will be rewarded with silver and white. ”

Thank you.

After Zhu Yuanzhang left, Zhu Yunwen said excitedly: "Today's inference is very successful, everyone has worked hard, send someone to send the sand table to the Qianqing Palace in a while, Qi De, you arrange someone to make another accurate, and send it to the Qianqing Palace when it is done, of course, we also need an accurate one here, let's do it together, but it should be smaller." ”

"Qi De, Master Huang, you are responsible for writing the chapter, recording today's deduction, with pictures and texts, show it to me after writing, and if it's okay, I'll show it to Grandpa Huang."

"Next, everyone will rest for two days, and then we will continue to refine the deduction, and we will gradually increase the number of people needed."

The crowd was ordered to disperse, and it was indeed too tired.
